Explain the figurative language Juliet used in line 25-26 and how it relates to a theme of the excerpts

Figurative speech from William Shakespeare's "Romeo and Juliet" Act II, scene II that Juliet used in line 25-26: "What’s in a name? that which we call a rose/By any other name would smell as sweet; " means that the name isn’t our essence. Rose would have the same fragrance even If it would be named differently. This figurative speech relates to the theme of the excerpts comparing Romeo to a rose. Romeo would still be himself even If he was named differently. His essence won’t change as rose wouldn’t change its fragrance even If would be named differently.
